初中情态动词讲解及练习题
情态动词表示语气和态度。

有实际词义,但是没有单复数等词形变化。

后面通常加动词原形中考主要考查can,must,may,need四个情态动词。

除此之外,表示必要性的情态动词还有should,应该,这个语气比must弱,还有
易考点:
一.比较have to和must:
1) 两词都是'必须'的意思,have to表示客观的需要,must 表示说话人主观上的看法,既
主观上的必要。

My brother was very ill, so I had to call the doctor in the middle of the night.我弟弟病得很厉害,我只得半夜里把医生请来。

(客观上需要做这件事)
He said that they must work hard.他说他们必须努力工作。

(主观上要做这件事)
2) 在否定结构中:don't have to 表示"不必" mustn't表示"禁止",
You don't have to tell him about it. 你不一定要把此事告诉他。

You mustn't tell him about it. 你一定不要把这件事告诉他。

二.肯定句中,表示推测,语气最强的是must,但在否定句和疑问句中,表示怀疑,猜测,要用can’t. (mustn’t禁止,不允许,不能用来表推测;can’t 不可能)
There is someone knocking the door. It must be Tom.
It can’t be Tom in the classroom. Because he is ill and he doesn’t come to school today.
三.情态动词的回答
1. 以can开头的一般疑问句,其肯定和否定回答分别用:can和can’t。

(Could也是)
2. 以may开头的一般疑问句,其肯定和否定回答分别用:Yes, you may. / No, you mustn’t.
May/might表推测时,语气最弱。

表建议请求时,语气最委婉。

May 也可以表示祝愿。

---May I go now? ----Yes. You may. / No, you mustn’t.
We may go to Shanghai, but we are not sure.
May you success!
3. --- Must I finish the project today? --- Yes, you must. / No, you needn’t.
四.其他
Shall 用于第一人称,表示征求意见,询问。

Shall we have lunch here?
Should表示义务责任。

We should obey traffic rules.。
